(GRANTED UNDER'THE PROVISIONS or THE ac 'r or Manou 3, 1921,41 STAT. n., 1313.)

To @ZZ 'whom it may concern.' l l Be it known that I, HENDRIK Anm TEM- rnLAAr., mechanician, a subject ofthe Queen ot the Netherlands., residing at Tandjong- Karang, South Sumatra,' have 1 nventedcer-K` tain new and useful Improvements 1n Teal Leaf-Rolling Machines (for which `I have` tiled an application in the Netherlands,

` machines are provided with a pressure device consisting of la piston adapted to be;

pressed bv a screw spindle on tothe tea!y leaves. Machines of this kind have the` .drawback that during the periods in which rollingT is executed without pressure, the piston closes the cylindrical tea storage receptacle at its upper side, thus preventingthe leaves frombeing exposed to the strongly desired cooling action. l

It would be possible toraise the piston to such extent asto leave the tea storage receo tacle Jfree `by increasing vthe height of the pressure device However this causes the practical. drawbackthat the machine as a whole obtains an undesired height. This is of' very great importance with so called double acting'v tea leaf' rolling; machinesfin which the storage receptacle also executes a circular motion. Y y

Devidson perceivedl these drawbacks and tried to correct them byV constructing his,y

fopen top roller in which a' constant pres-` sure on a continuously7 varyingl part of the leaves is exerted by plough shaped membersv arranged at the inner wall ot the storagere;` ceptacle. these members causing a partial compression and at'the same time a circular tion of the tea leaves;l However, these machines have proved to be'unsatisfactory in practical use as they do `not rolled product. v

The rolling machine .according vto the invention presents the advantages' of compact construction, quick action and the obtaining of a perfect product. These advantagesare obtained by arranging two opposite side give al well? walls ofthe storage receptacle. which has a-v square cross section. in such apivotable manner that theyr may be lowered 'inwardly' and brought under pressure. In its open -position the storage receptacle Voccupies but,` a:

small height andv an excellent cooling 'action is then exerted on the tea leaves. i The `invention yis explainedby the accompanying drawing whichillustrates the ma! chine'in side elevation'and in plan view. v

The tea storage receptacle consists of two portions a, b. :the lower portion a having;3 a

circular cross sectionthe upper portion "a i square section. The receptacle is supported` at three points c, eZ, e, the two formerbeing 5 and may be rotated by 'Ineansfof thecr'a'nkf v` journal bearingswindiscs runningon balls f which actsasla support for Z andis driven."v f i VJfrom the sha-ft c1` by means ot'a bevel tooth wheel gear.' This crank alsodrives the lower table 7a which is supported in'a similar way.

A combination of the kind defined by claim `1 in which the means for moving the free ends oi lthe plates towards one another includes threaded spindles and operating wheels. f

3. A tea leaf rolling machine including` a table movable in a circular path, means for moving said table in a Circular path, a receptaele arranged above said table and hav# ing an open bottom*7 means for moving said.V

receptacle in a Circular path, said receptacle having opposite side Walls formed opivotally mounted plates7 and means for moving the free ends of "said plates towards one another whereby material carried by the reeeptacle maybe packed. v

In testimony whereof I aflix my signature.
